A Markov chain yog stochastic qauv piav qhia txog ib theem zuj zus ntawm cov xwm txheej tshwm sim uas cov qhov tshwm sim ntawm txhua qhov xwm txheej tsuas yog nyob ntawm lub xeev tau txais hauv qhov xwm txheej dhau los.

Cia li saib qhov no, koj txhais li cas los ntawm Markov saw?

A Markov chain yog ib txoj kev ua lej uas muaj kev hloov pauv ntawm ib lub xeev mus rau lwm qhov raws li qee qhov kev cai yuav tshwm sim. Lub ntsiab yam ntxwv ntawm a Markov chain yog tsis muaj teeb meem li cas txheej txheem tuaj txog ntawm nws lub xeev tam sim no, lub xeev yav tom ntej tau raug kho.

Ib tug kuj yuav nug, qhov txawv ntawm Markov saw thiab Markov txheej txheem yog dab tsi? Cov Qhov sib txawv ntawm Markov chains thiab Markov txheej txheem yog hauv index set, chains muaj lub sijhawm tsis sib xws, txheej txheem muaj (feem ntau) tas mus li. Random variables zoo li Guinea npua, tsis yog npua, los yog los ntawm Guinea. Random variables yog functions (uas yog txiav txim los ntawm txhais).

Tom qab, lo lus nug yog, Markov saw siv rau dab tsi?

Markov chains yog siv rau xam qhov tshwm sim ntawm cov xwm txheej tshwm sim los ntawm kev saib lawv li. lub xeev hloov mus rau lwm lub xeev, lossis hloov mus rau tib lub xeev raws li yav dhau los. Peb ua tau. coj huab cua ua piv txwv: Yog tias peb arbitrarily xaiv qhov yuav tshwm sim, kev kwv yees hais txog qhov.

Dab tsi yog homogeneous Markov saw?

markov - txheej txheem graphical-model graph-theory. Kuv kawm tias a Markov chain yog ib daim duab piav qhia txog yuav ua li cas lub xeev hloov lub sijhawm, thiab a homogeneous Markov saw yog xws li ib daim duab uas nws qhov system dynamic tsis hloov.
